Oiaims. (Cl. ale-43:):

This invention relatesto new and useful improvements in cleaners andmore particularly to a device adapted to catch and hold scale, rust,dirt and all foreign matter that might accumulate or be found in thewater or liquid in the cooling system of anywater, or other liquidcooled internal combustion engine or motor.

The primary feature of this invention is to provide a device of thecharacter referred to having a pair of removable filtering elements ateach end thereof which are adapted to specifically catch and hold allscale, rust, dirt and all foreign sediment or matter in liquidscirculating through a cooling system.

Another important feature of this, invention is to provide a device ofthis character having said filtering elements adapted for easy and quickremoval therefrom for replacing with new elements.

A further feature of this invention is to provide a deviceof thecharacter referred to that is efficient and reliable in operation,relatively inexpensive to manufacture and otherwise well adapted for thepurposes for which the same is intended.

Other objects and advantages reside in the 5216133115 or constructionand operation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming parthereof, wherein likenumerals refer to-like parts throughout, and in which:

Figure 1 is a perspective view of the device constructed in accordancewith the present invention.

Figure 2 is a vertical longitudinal sectional view taken through. thecenter thereof.

Figure 3 is a sectional view taken on line 33 of; Figure, 2;

Figure 4 is a sectional view taken on. line 44 of Figure 2.

Figure 5; is a, sectional view taken: on line 5--5 of Figupe 2, and

Figure 6 is a sectional view taken on line 65-45 of. Figure 2.

Referring now to the drawings in detail, wherein for the purpose ofillustration, we have; dis;- closed a preferred embodimentofi theinvention, the numeral 5 represents an outer filter casing ofrectangular shape having its end edges bent outwardly to form flanges 6.

Frictionally held within each end of outer casing 5 are a pair of innercasings 7 and B.

The inner opposing ends 9 and H) of said inner casings l and 8 areprovided with perforations H and I2 toward one side of said ends.

Connecting the inner ends 9-: and 10' of said inner receptacles 'I and 8is a bafile plate i3 which is spaced slightly above an inlet nipple M inthe bottom of the outer casing at its center.

The lower portions of casings 1 and 8- are providedwith inlet chamberst5 and i6 having pref erably arched openings H at the inner ends of saidchambers.

The inner casings are similar in construction and a description of onewill sufice for the other.

A longitudinal bafile plate i8 is suitably secured at one edge 1-9 tothe inner end of the inner casing at its imperforate side and inclinestoward the perforate side and the outer edge 28 of said baflle plate i8is spaced slightly inwardly from the outer end of the outer casing; Anopening 21 is provided in the upper wall 22 of inlet chamber l-5 on theside of bafile plate i8 adjacent the imperforate sideof the innercasing.

An outlet nipple 22a is provided in the outer casing 5 slightlyabove-baffle plate t3.

A pair of end plates 23 and 24 having centrally located sockets 2-5 andribs 26 radiating from said sockets to the corners of said plates isheld against the ends of the outer casing 5 by a pair of clamps 2-7- and28 having adjustable set, screws 29- at the center thereof which fitinto sockets 25, said clamps 27 and 2-8 having clamping arms 30radiating from the centers of said, clamps which are adapted to clampsaid plates 23 and H to the flanges 6 of the outer casing as shown inFigure 1 of the drawings.

In operation, water, or other liquid used in, the cooling system entersinlet nipple 14', under pressure from the water pump, or by gravity, andstrikes upwardly against baffle plate l3 and is diverted equally througharched openings 17% into chambers I5 and Fit respectively;

The water in chambers l5 and [6' is then forced upwardly throughopenings 21 intheupper walls 2:2 ofsaid chambers and passes throughfiltering material 3| loosely packed at-the imperforateside of'bafile I8collecting sedimentation, at the side. of the baiiie provided with thefiltering material, the water then passing around the end 20 of saidbafile l8 into the perforate portion of the chamher and throughperforations I I and t2 and then discharged outwardly through outletnipple 22a.

The inner casings are easily and quickly slipped out of said outercasing for replacing when desired.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understandin of thecontally disposed outer casing having its ends open, an inlet extendingthrough one wall of said casing, an outlet arranged in the opposite wallof said casing, a pair of inner casings carried by the end portions ofsaid outer casing, horizontal partitions in the inner casings to provideinlet chambers inthe lower portion of said inner casings, a baflie plateextending longitudinally in the upper portions of said inner casingsdividing same into a sedimentation chamber and an outlet chamber, saidpartitions having openings therethrough leading to said sedimentationchambers, filtering top, a pair of inner casings-carried in the endseparating the inlet from the outlet, an inlet chamber in the lowerportion of eachof said inner casings having openings adapted to receiveliquid entering the inlet and impinging against the baflie, the upper.portions of said inner casings providing sediment collecting chambershaving openings leading from the inlet chambers, and filtering materialin said collecting chambers, the inner ends of said inner casings at thesediment collecting chambers having an opening through which thefiltered liquid passes to the outlet.
